Membership plugin - cannot see renew option on account edit page.

Hi

I am setting up the Membership plugin, but I am a bit confused as to how members renew.

Reading the documentation, they can renew on the "account" page. But I cannot see the renew option within the "edit" box. What criteria need to be met for this to appear?

Do they need to go through a payment gateway first, i.e. not initially be placed on a particular subscription by admin?

I have set my Renewal period limit to 365 days.
